Gmail moving mail

[Dick7Access]

Why is Gmail moving old messages from labels I put them in back into my inbox?
Everything I googled wants to tell me how to move them. I know how to move them, I just want them to stay there.
Any ideas?

do they say "follow up?" next to the titles of the emails?

google automatically places that next to items in the inbox after ''x'' days if you haven't sent anything. thought it might be related.
